Geneforge

In Geneforge, players assume the role of an apprentice Shaper, a sect of mages who can create living creatures through force of will. The apprentice is cast away on an island abandoned by the sect 200 years prior. The island contains groups of the Shapers' creations, who have formed their own ideologies regarding the sect. The player must escape after dealing with the forces at work to steal the Shaper secrets abandoned on Sucia Isle. Source: Wikipedia, "Geneforge," available under the CC-BY-SA License.
