Hello Everybody i am new here

I really like Beyond divinity i did all quest beside 1 in academy level 3 where need to get third doll.
I wanted to ask:
i Finished the Beyond divinity,and i didn't really understood the Story( i understood but not all the story)
I didn't Finished the Divine Divinity only saw the ending.
The baby from Divine Divinity Wasn't killed and is it a Demon of lies or chaos Aka Damian The Death knight right?
and in the end of the beyond Divinity Movie he is says:
"...The taste of freedom is Sweet indeed So many nights i have spend dreaming to Destroy The one Who Imprisoned me the one who extinguished a single Candle of Light in my life i have Become the Darkness it self Revenge Will be mine" *Going Up Stairs"
Who imprisoned him?
why he imprisoned him?
why he want revenge?
where he went?
What happened to paladin From Beyond divinity(Hero you play as all game,i have almost beat death knight and he Rifted me away.)
what is Nemesis or Revillon
Does Divinity 2 Have the Death knight? or Damian(don't Tell me Spoilers just tell if he in the game)
p.s i want to beat Beyond Divinity on Hardcore now i know that i will have to fight Death knight and i will focus more on my hero( i really liked death knight more than my hero)
What Skills to chose?(i chosen Bow for hero and 2 handed slashing for DK but now i see people said to let DK use Bow)in academy i had 2 handed Shadow for DK and i did Slashing :S forgot to change it)
when i beat the game i had 60 str 49 agi 45 Con For bow but i changed to 2 handed shadow becouse i had powerfull Sword and i didn't did damage to death knight with Bow.
What Stats i need for Bow and what stats for 2 hand slashing? STR AGI and CON? and what Intial skill to chose when i start the game(warrior and warrior?)
Sorry For long Questions,Please help guys.
