The CT dates back a few thousands years, we know this because the Allagan Empire was destroyed thousands of years prior, before the order of Magi (those responsible for the Void Ark). So even though he was a part of the Empire before turning against Xande's corrupt rule before being experimented on he could've 'stopped' Odin.
It's been stated that the Summoner Wiyu was the one to defeat and seal Odin. The original Summoner relic quest covers the event in a little detail.

This thread has perplexed me though. It was seemingly created post 3.0 yet is debating things we've known for quite some time. I don't get why there is a debate here about if eikon = primal when the very text that sparked the discussion is very clear that they're NOT the same thing.
