Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Mods How & Where will I start making a small Adventure?

Many thanks JecklynHyde & Libertine for the help and opinions

I've the Kickstarter Box and play via Steam, but I can't find the "Divinity Engine" !

I've looked yesterday into my Steam account and I believe (but not sure!) I must download this Divinity Engine via "Tools",
is that correct ?

And another question I've :
with the Kickstarter Box I bought I've the opportunity to make/create my own Summon (or just "name" my Summon"?) ... but how I can start this all working, ... I don't know ...
