I see that they got their "telepathy" by developing radio mind control.  Is this a trait exclusive to the more advanced colonies only?

And I like that you gave them a divisive nature instead of mindless hive unity.

Here is the guidelines for aliens for the second edition IC:

[hider=Aliens!]

Your perspective as an alien is the most unique perspective of the three, for to be an alien is to be of many potential perspectives all different from each other due to being so biologically unique.

Your biology and life style dictates a way of life suited to the world you evolved on. 

When making an alien, focus on making an interesting alien form that is a believable product of the world you want to set up shop.  Avoid trying to make something to win a game.  Think in terms of asymmetrical advantages and disadvantages instead of trying to match the tech of the humans or custodians.  Be creative about this, try to avoid high tech solutions to the human problem.  For your focus is on having a cool culture, strange tech and on making them feel like aliens.

When making an alien, keep the species app separate from the civilization app as all species made are public domain (unless there is some lore reason why it can't be).

For a species is treated as a parent to the civilization, and thus a species can have multiple civilization along with all manner of less developed groups (or your sapient may just be 100% tribal, in which case you don’t need a civilization app).

NPCs of your species can be assumed to exist somewhere on the planet you base your species on.

Like with humans, should multiple players share a family of sapients who know each other well, technology is easier to share between them.  Tech is harder to share between sapients with larger differences, though you can always trade anyways.
You can set up your sapients anywhere a complex biosphere is.

Sapients in general should avoid having space travel unless there is a good reason for it. 

In exchange, you get to have much better adaptations to the world you set up shop on and being able to build up the planets themselves on a detailed level.  Humans do not get to do this to the same extent (To humans: you do get to define some select species if desired).

For you also get to define the environment, fauna, flora and so forth of the regions you want your alien to occupy.  So please be someone who likes making strange, horrifying creatures and landscaping if you seek to be an alien.

In regards to aliens and custodians...  Well, the custodians can communicate with ANY species.  The custodians likely will impact you in some fashion, how so depends on the arrangements you come to with a custodian player.
