In her room that night, Talashia filled a small wooden cup with a measure of water. Into the water she poured some white powder taken from the Alchemist's shelves, and stirred with a small glass rod.
She murmured in the breathy language of Auran, invoking the knowledge and secrets carried on the winds; whispers of everything ever breathed still echoing, if only faintly, through the air.
Then she drank the water, and immediately grabbed the staff, holding it up as if showing it.
Talashia waited there then, straining her ears for the whispers. And slowly, the whispers came...
(basically casting Identify on everything magical but the potions, which I'll try to ID with Spellcraft checks.

)
