Dral:
Dral's goals are not important here. We can make up anything we need for either him staying or him leaving.
Dral is not unplayable and I'm not bored with him, but I'm concerned that I will get bored with this ogre as part of the group. If it's just for the next couple of encounters, I can probably just deal with it.
If it's longer than that, then I'd rather restore the game to state it was more designed for, and take over the ogre. Dral would go away in a way that makes sense to everyone.
To clarify. The ogre is a chaotic creature by nature, and has been enslaved, once it has done it's task, as clarified in GIANT to grock, it will depart. It is not a player, it is merely a way to reward a clever way to go about an encounter and foe. You passed, you get rewarded, but not permanently.
That said, I hope you feel better Dral, but otherwise do PM me and I will advise further, as I do not wish for this to cause issues.
