Seeking Campaign Advice Related to Classic DnD Elements

[DocSER]

I am working on a new campaign. While I won't bother you with the details, I wanted to fish for some ideas for pinning key elements to classic DnD references.

I am inspired by my vague recollection of a reference in the original Manual of the Planes to the dangers of traveling in the positive energy plane. While I am not sure about the specific danger (healing until you pop, or something like that), I want to use the possibility of excess positive energy being a threat as a major theme.

The problem is connecting a classic antagonist to this theme.

I was thinking of retro-fitting a classic reference -- but this may be too much of a stretch. I figure I will be able to tell by the flame messages about how I am ruining DnD.

Anyway, I was thinking of using Kyuss as an antagonist and use his interest in the Age of Worms as an attempt to unleash unchecked positive energy in a destructive way. I know he is associated with undead (usually, themselves, related to negative energy) but this makes his interest in worms (living things) difficult to understand. If Kyuss animates with positive energy, his interest in a key piece in the "circle of life" makes sense and I can appropriate him for a positive energy related campaign.

Does this make sense or have I just tricked myself into thinking it is consistent?

Any other ideas for a classic antagonist for a positive energy focused campaign?

Man, you need to check out the old Planescape Monstrous Appendix III! There are a couple elemental bad guys which are radiance/positive energy inspired that you could convert to the system of your choice. If you can't get ahold of that book, I can look 'em up for you.

I was in a campaign where Lolth was slain and overthrown. With her last moments she unleashed a dying curse that opened a rift to the negative energy plane. We spent a good chunk of the campaign trying to seal the rift. You could use that, a dying curse, as an idea for how the positive energy is bleeding into the world.

Mummies, though undead, were associated with the positive material plane. It's not too much of a stretch to associate Kyuss there as wel. If you consider the worms of Kyuss to be positive energy entities that revive the bodies of "sons of kyuss" - without the dessicated flesh to bleed off the excessive positive energy they are ripe with, they would "pop"; which to the eyes of others may seem that the worms falling from the bodies just melt into a slime trail or seem to just "vanish" as they atomize.
