Tactics for Necropolis.

and right at the start, there's no one better than Galtran in Necropolis, because he brings a bunch of skeletons with him and also gives them a speed bonus.

If there are no rules, then Isra/Vidomina look more interesting in the long run than Galtran. IMHO. Diplomats are strong, no doubt. But Necromancers can also get diplomacy :) Conflux mages with upgraded fairies are also very strong.
