Discussion Characters / Excalibur

As another followup for housekeeping in addition to the spoilers stuff. I added some more characters as they were of parts comparable to some of the other minor ones listed, at this point would we like to talk about creating groupings? I'm not sure if it looks awkward now having the dozen without a clear order on the page.

I think this page could use some discussion on where or if at all to begin use of spoiler tags. Somethings that don't happen until the very end (Mordred killing Morgana) are left open on certain tropes (Final Boss) while his birth is blanked on others. Having recently started adding to this page I'd like to ask if we want to consider putting a spoilers off heading for consistency?
