At Simsl3gacies.com, which is currently just a file directory, access the sub-directory "Sims Asylum" to find the files that were exclusive to the Asylum. It is second-up from the bottom of the directory.
Will have a few more things uploaded this weekend based on some requests I've gotten recently. Another series of moons, a pose pack, and maybe the dragon mods too, if I get a round tuit.
