Xeno Influence is the final Thalan-unique Good tech.
It includes the Xeno Influence starbase module.
Which requires the Insurrection Coordinator module.
Which requires the Cultural Insurrection tech.
Which is under the Xeno Entertainment tech line.
Which the Thalan don't have.

So the Thalan can't actually install the Xeno Influence module.

One other idea. The Singularity Armor is a great Thalan starbase module, and makes me think - would it be possible to have a building with a significant +soldiering bonus? It would only apply to the world it's on, could be an improvement under Mechanized Warriors. This would help the Thalan, with their limited population, to withstand ground assaults without making their own assaults completely overpowered.

Thanks!
