I've been suspended from the Mages Guild and have to locate a Ramus Polus and thus far, have had no luck. Does anyone know where this character can be found?

Wow. Hes always in the first room at arcane university. The one you dont need to be in the guild to go to.

Raminus Polus isn't always there. Sometimes he is sleeping in the Mages Quarter's. If you aren't in the guild ... the lobby of the Arcane University is the only place you can see him.

Thanks, I did indeed find him and he's sent me on what I thought would be a simple quest but which, has now turned out to be a futile endeavor. It seems I've collected every plant in Oblivion EXCEPT the two I require: dragon's tongue and redwort flower. Any idea where these plants can be harvested?

you can buy dragon tongue from the alchemist in leyawinn i think, i know there is one mage guild alchemist that has that but im not sure
