I wanted to have both of them in my party (mainly good, neutral-good). As soon as we heva seen Viconia, Keldorn started to object - not to save her I mean - he has some racial problems

Will they kill each other, or could I keep them?
And my second question: Will Valygar get druid spells? - it is not written that Stalker does not have druid spells, it is written only that he has some mage spells - do they exclude each other?
Thanks
