Newbie Question: Joining The Living And The Dead

[Managarm]

I've created a list with the summoners (creature summonings with magic skills) available in Death/Nature schools for reference purposes.
Although I've tried to make it as accurate as possible, expect some flaws because I found some difficulties understanding some bits of the data I used (e.g. the random magic skills).
The data was taken from in-game menus plus Sunray's and Edi's databases.
Here we go:

Does somebody know how to invoke the "Ancient Presence"? Besides it has a unique name, it isn't tagged as a Hero, so it should be available to all the Nations (I presume)

I think the best Nation for supporting a hardcore death/nature summoning strategy is EA C'Tis: they start with +4 Death and +2 Nature gems and have a couple of interesting Pretenders with starting Nature and Death Magic; Father and Mother of Serpents.
