In June 2008, I began a new Greyhawk campaign, using the newly released 4E rules.

In July 2014, that campaign will end.

It’s now less than a fortnight until that day. During the course of the campaign, the adventurers have delved beneath Castle Greyhawk (Zagyg), have fought the necromancers of the Shadow Forest, have discovered a strange, forgotten temple, have explored several versions of the Tomb of Horrors before finally defeating Acererak, have explored a crashed, flying castle (The Lost City) and rescued a god, and, in the very early days of the campaign, had one of their own turn on them.

Now, in the finale of the campaign, they’re facing that character in the depths of the Temple of Elemental Evil.

Archibald the Traitor has fallen far – a tiefling warlock, his initial dabbling in darkness has led him eventually to the worship of Tharizdun. His plans for releasing the chained god have been dealt a severe blow by the party, but he still might be successful…

In stark contrast to how 4E NPCs are normally built, I’ve statted out Archibald as a full 30th level PC. He’s a massively complicated character. He’ll have allies – lots of allies – and I’ll likely allow recharging of Encounter powers half-way through the battle.

Is this overkill? Possibly, but he’s been such a recurring feature of the campaign it’d be a shame to have him be nullified in one round.

The next step is to find him some appropriate allies. And then some miniatures and some Dwarven Forge Dungeon Tiles to make the final battle really special!
