Yeshe is a badass. A slightly tweaked Paladin of Slaughter (aura of despair sits better than debilitating aura), with Favored Soul and Cosmic Descryer. Uber-epic 50-point build, with +5 inherent bonuses. She gets a bonus feat instead of wings. She also gets the widely-hailed-as-broken Cosmopolitan feat; what can I say – a DM's got to do what a DM's got to do.
It was important that the big 3 – Temenun, Sibud and Yeshe – should be approximately equal in power; their primary defenses are rather different: Temenun's SR is very high, Sibud has comprehensive immunities and Yeshe has incredibly robust saving throws.
Temenun's power is barely enough to assure his pre-eminence, and either Yeshe or the Vampire might displace him. The Rakshasa's magical seniority and deific suavity hold things in a fragile balance.

The Pillars At Khu and Yeshe's Binding Suite
The Pillars at Khu were destroyed long ago, and even their exact location is debated – presumably Yeshe, having made them, would remember where they were.
I wanted different methodologies to be available for those conjuring powerful extraplanars, and the summon seed wasn't cutting it. Finding an arbitrary non-balance with epic spells is always fun :/
Yeshe's method would be through specially constructed circles – pristine areas formed from raw magic – which would then serve as the basis upon which subsequent magic could be worked. Like verdigris tsunami, Yeshe's conjure edifice cheats by applying an area factor to the conjure seed; in fact, the whole suite 'cheats' in order to bypass normally prohibitive Spellcraft DCs, and becomes the mechanical basis of a kind of epic goetia which relies on deceit as much as force of will in order to gain compliance from called entities.
Not counting the initial investment of XP for a suitable site, to call and bind a named demon – such as Pazuzu – costs Yeshe over 7000XP, which seems reasonable enough.
Conjure Edifice (DC 84): conjure (+21), fortify (+17); change area (20ft. radius) (+2) increase area by 100% (+4), permanent (x5); extend casting to 30 days (--80), burn 5600XP (-56).
Yeshe evokes thirty slender adamantine pillars in a circle with a diameter of 80ft. – each pillar is around 60 feet high, and each is exquisitely carved in multiple likenesses of ugras as depicted in Cheshnite lore. To succeed at the task, Yeshe must make a DC 40 Craft check. Use of the fortify seed allows the edifice to subsequently receive an additional tied effect from unhallow, and to act as a reception site for the gate shroud.
Impressing the Edifice: the edifice is unhallowed, and an inward-focused magic circle and dimensional anchor are tied to it. It now acts as a thaumaturgic diagram.
Gate Shroud (DC 84): conceal (+17), delude (+14), ward (+14); nullify augury (+4), commune (+8), divination (+6), true seeing (+10), and foresight (+16); +20 Save DC (+40), +20 spell penetration (+40); extend casting by 10 mins (-20), use pillar edifice (ad hoc –20), burn 4500XP (-45).
Illusion (figment). This spell prepares an edifice for a subsequent casting of a gate spell; for 200 minutes any gate spell cast at the location of a gate shroud is perceived by the target creature in the most favorable way – unique beings usually under no compulsion to respond to the gate will desire to do so unless they make a Will saving throw (DC52). If the target creature is in possession of the ability to otherwise perceive the true nature of the gate's purpose, or the gate shroud itself through augury, commune, divination, true seeing or foresight, that ability is suspended for the duration of the spell.
(Creatures gated into the edifice are confined within it in the same manner as a planar binding. This allows a more leisurely casting of the next spell):
Dominate Ugra (DC 84): compel (+19), ward (+14); nullify protection from evil, magic circle against evil (+4), and mind blank (+14); +20 Save DC (+40) +20 spell penetration (+40), stricter compulsion (+10); extend casting 10 mins (-20), burn 3700XP (-37).
Compulsion [Mind-Affecting]. Any creature who is the target of this spell is dominated for a period of 20 hours. Creatures protected by protection from evil, magic circle against evil or mind blank have these protections suspended for the purpose of dominate Ugra. Creatures receive a saving throw (Will DC 52) to resist the effects of dominate Ugra; Yeshe gains a +20 bonus on her caster level check to penetrate a target's SR.
