I agree - they cant just be floating stone pyramids...

OK reposting ideas from previous thread (glad you like them):



In terms of inspiration, how about we add a few races from fiction. In addition to the obvious one, I propose the Orz from Star Control, and the Vorlons from Babylon 5. Both are mysterious, possibly involved in our original evolution, and so hideously advanced that it's difficult for them to comprehend us, let alone vice versa.

How do you get vital war intelligence from a captive? A human would question and possibly torture the captive. The Phaerons digitally upload the enemy brain and reprogram it into cooperation. The Frogulans? They follow your worldline backwards and forewards to learn your entire history, planting sensor portals all along your existence, just out of sight along some hypergeometric pathway. They either release you, so your worldline can intersect with the enemy army again for still more information, or simply suspend you in time until needed.

They're not cruel, simply efficient and have a much longer and broader sense of the universe. They (reluctantly) act as soldiers on the scene themselves simply because their last attempt at a servant race ended in the Phaerons. They don't really have the stomach to control a race the way the Stygians' masters do. Their empire is as large as it needs to be, in fact, probably too large because it's a legacy from a time in their history when they needed to use naturally occurring space-time rather than simply manufacturing it themselves. Meanwhile, they've been in a war with various higher beings, including the Stygians' masters, for millions of years-- most of that in the future or quasi-time, and are trying to avoid being out-flanked into a world-line where the other minor races either become pawns of their enemies or ascend and destroy the Frogulans themselves. The very few volunteers from each generation who want to be warriors are more than enough to deploy vast armies, aggregated over thousands of years.

In terms of factions, the Frogulans are politically/culturally unified in a conventional sense; however, different points in their unimaginably long history (and different versions of them from different timelines) produce vastly different policies, color schemes, strategies, etc. These are called "epochs" and are for all intents and purposes factions. Since they all travel in time, and become more or less close to the current timeline depending on how the war is going, many epochs can be intervening at once in the same event, sometimes against one another, and sometimes even actually fighting one another. It's not uncommon for a frogulan emissary to casually reveal that he's dealt with you before in other timelines, or even to mistake you for an alternate "you". They'll sometimes do this on purpose to get an edge in negotiations; sometimes they want some stupid piece of trivia because it'll be useful maneuvering against you in some other timeline. To the frogulans, these are like different cities in the same country. To humans, it's arcane, abstruse, and a little scary.

...phenomenal...

I hab similar thoughts. Something like a link network between the Tzacol. The drone concept makes a lot of sense to me espacially if they are bio-engineered.
In the original fluff the Tzacol are masters of genetical engineering and have altered the evolution of many races in the universe. Even taken some creatures from earth (the orangutan like race from old 40k fluff).

I like the idea of biological constructs mixed with their absurd high level tech. So everything has a organic feel. The problem with a link network and organical weapons is that is very similar to the tyranids. But if the rules are different enough it could work very well.

As there are only very few Tzacols left the army structure should reflect that. Few UNits that are powerfull but ridiculus expansive. So a very small army.

For example (No real army list just a basic structure ):

Tzacol Engineers
The Engineers are the Backbone of the Tzacol race. The are building an intergalactic network between there minds. They funciton as an communication hub for the few Tzacols throughout the universe.
On the battlefoield they provide the communication between ground- and spaceforces and there homebase.
All Tzacols are psykers (?) but the Engineers are using a spherical construct that further enhances their powers. With it they are able to evoke forces that can even destroy titans. But using this much power will reduce the mindlink to a mere whisper nothing more than a radio transmission. All local mindcommunication is focused in one engineer. This Tzacol is the local Mindhub that concentrates one cummunication with the mindnetwork. If this Tzacol dies the communication to the off planet hubs is broken and a lot of the longrange suports is without information. And longrange Suport like Warpfolds are not longer possible.
When there is great danger to the Tzacol, some engineers are fusing with there bigest bio-constructs. These machines are filled with enhancers, similar to the spheres, and give the fused Tzacol abilitiys that can destroy entire armys alone. But this equals a suicide mission as using this powerr will destroy the consctruct and the Tzacol alike. Only very few where able to survive the fusion and even less are able to use psy powers ever again.

Abilitys:
- Mindlink (connects all Tzacol on the batlefiedl) - all Tzacol can use the sight of all other Tzacol units (overpowered?)
- Mindhub (only one Tzacol per army can be the mindhub)
- Psy powers - some kind of support powers and one or to destructive powers
- Warp fold (only when mindhub is alive) - units/detachments can be teloported
-

Tzacol Warriors
Some Tzacol are chosen to support the Engineers in battle. These Individuals are embedded into a powerfull Armor. These Suits are the best infantry the Tzacol can field and the only Tzacol that are trained for combat.
These warriors are highly adaptable and have the best equipment to their disposal.

Abilitys:
- Mindlink (connects all Tzacol on the batlefiedl)
- lots of cool weapons

Constructs
These are biological engineered cyborg things. From infantry and tanks to titans.

Drones - Mostly cheap massproduced infantry/walker constructs

Skimmers - light tanks, assault constructs

Heavy Skimmers - Artillery and support units like shield generators

Flyers

Heavy Flyers

Titan Skimmers

Titan Flyers?
