The maintainers are beings of pure force. They can exist only in Azrantia, the demiplane controled by Lord Azratax, as they are as much an extention of that plane as independant creatures. A maintainer appears as an indistinct sphere of energy 5 feet in diameter. They exist on both the prime plane and the border ethreal at once, though they can move fully to the ethreal plane, becoming incorperal, for up to 10 minutes per day. Doing so is a standard action, as is ending the effect. The maintainers are all telepathicly linked to eachother and Azratax, Keesha, and the guild rulership council (and can communicate with them at infinate range), and can communicate telepathicly with anyone within 100ft. They cannot speak. They are instantly aware of any damage to the forcewalls on the border of Azrantia and attepts to dispell or disjoin the levitation effects on any of the floating platforms (and other attempts to inflict major damage on the plane). They will respond to any attack on the plane immediately, using thier jaunt ability.

COMBAT 

Spell like abilities (Sp): At will: Arralon's force missile CL12 (this is thier primary attack form, and they can use it from incorperality)
2/day: Keesha's force beam CL12. Sorcerer spells: 6/7/7/7/6/5/3; Spells known: 9/5/5/4/3/2/1. Maintainers commonly know disintigrate, wall of force, and other spells that work with force.
Spellpool access (Su): Any maintainer may use the spellpool of Azratax's magic guild as described in T&B and MoF for spells up to 6th level, with no limit on spell levels per day called (though they must still pay back spellpool debt).
Melzan's Frequent Jaunt (Sp): Maintainers constantly act as if under the effect of this spell (see MoF) cast at the 12th elvel of ability, able to teleport 85 feet as a move-equivelent action.
Wall of Force permenency (Su): When using permenency (called from spellpool, most likely) to make a wall of force permenent, they need not pay the XP cost. This is often nessesary for repairing the plane.
Empower spell (Ex): Maintainers are treated as having the Empower spell feat, and can cast empowered spells (though they use a slot 2 levels higher, as usual).
