A Crossover I am looking foward to...

[Gadodel]

Essentially, Iuz the Evil; in attempt to reclaim power and prestige has unveiled his latest plot. Iuz has sent his greatest agents, whom in turn lead some nasty Fiends; to other planes and worlds. The world of Abeir Toril (Forgotten Realms) has been targeted! Thereupon, his minions are to kidnap personalities of interest and note. Returning to Oerth, successful; shall grant any agent gifts beyond their wildest dreams...

Though, I do not know the author(s) of said story.

If I were an evil god, and I wanted to invade a new world, Abeir Toril is the LAST place I'd choose. How many ways can you get smacked by well-co-ordinated good gods AND territorial evil gods at the same time? I mean, if there's an upper limit, then Toril probably holds it.

Deities on both sides will be busy dealing with Fiends of all ranks...

Go to Krynn. Less gods there to smack down.

Yes this does sound cool. Very cool. But I have to concede the Logic and tactics that others have pointed out.

The Seraph of Earth and Stone

Go to Krynn.

Attack via Krynnspace with an armada of Scro (space orcs).

Krynn has no orcs and the things breed like rabbits so you'll soon populate the globe with a legion of fanatical worshippers.

Then bring Krynn's goblin/hobgoblin population into the fold by claiming that the Scro are their goblinoid superiors (an space-faring orc has gotta be superior).

Then manifest as the dead god Takhisis. Claim that you have been reborn. This way you'll dupe the draconians and chromatic dragons into joining your army. Hey, Iuz, duped the northern barbarians of Oerth he was the god Vatun so he must pretty good at it.

This part wouldn't work. Unfortunately, the rules for why are currently not posted.

In a nutshell, I worked on a revised version of Dragonhelm's Guide to Krynnspace with Trampas Whiteman. It was posted over at www.spelljammer.org but then Trampas had to move his site from www.dragonlance.com to www.dl3e.com and the revised version linked at the official Spelljammer website got lost. The version linked to above is the older, un-updated one.

The gist of all this is that the updated one included penalties for when any orcish creatures were in Krynnspace.

That said, the next campaign crossover I want to see is the following: A Manshoon clone from the Manshoon Wars flees to Oerth. However, Khelben the Younger (and maybe Mordenkainen) show up to blast the hell out of him almost as soon as he arrives.
