The current lab situation is as follows:
Stephan - Kallius' .
Daggin - Glendower's.
Mathius - Torsten's.
Rhiannon - Building.
Corvus - Building.
Fabrica- Building.
The last remaining lab is set up as a hospital, and the general consensus is to let it remain as such, provided a suitable Chirugeon or Physician is found.
So, Option 2 it is, while Albertus' lab is built. Look HERE for the arcane library.
Your lab, whose layout you do have some input will be built during the summer season. Also, basic lab equipment has been ordered; Anything special will have to be discussed with Deirdre and Angus.
