Persistent Spells
To give you a little demonstration (

) what Allyra is capable of, I have added a list of spells to the RG sheet, which will be running 24/7 (that is, unless something happens, which requires to use the spell slots otherwise).
Allyra will usually cast these spells in the evening, roughly 8~10 hours before preparing her spells for the next day.
Some of the
extended spells (namely
extended Mage Armor on Kira,
extended False Life on Kira, and
extended Overland Flight) are prepared directly with the metamagic applied, using the slots which have been left free (that are also used for a few other spells, like the Shield on Kira, See Invisibility on Kira, Rary's Mnemonic Enhancer and Energy Buffer). The extra slot from Rary's Mnemonic Enhancer from the day before is used as well, as is the Mordenkainen's Lucubration (to cast Energy Buffer twice). The remaining ten metamagic effects are applied using the incantatrix ability with the same name (using take 10 on the Spellcraft checks).
Metamagic Effect actually seems to be quite nifty with Persistent Spell. At some point I wondered, what good that feat would be for Allyra, since the +6 levels are pretty huge, if you only know 6th level spells (and the Endless ability, which allows to use it a bit easier, is still a few levels away

), but then I realized, that it works perfectly well in combination with Metamagic Effect, which she had, anyways. So, there you are.
Bye
