[@Shu]Can I ask you how the roleplay will work? Will someone function as a DM of sorts? (It's been a long time since I've been a part of RPGuild so I'm not sure if that's how things operate here still)

How combat focused do our characters need to be? Would a utility caster/support role be helpful or just still useless here?

Is there an official wizards of the coast handbook of any kind I could go find and read? They tend to be more detailed than anything the forgotten realms wiki has
