[Link to House Rules] A few creatures and races for review

[Knight Otu]

I have a thread in House Rules where I convert a few bits from a SciFi series to DnD. So far, I ended up with converting mostly creatures, and although Upper_Krust has already looked at them, I think it never hurts to hear (or better read) a few more voices.
The contents of the thread so far is a dragon, a swarm of aberrations, two humanoids and an outsider (devil).

If anyone wants to take a look, the thread is located here
