Liam will be able to summon objects, people, animals and plants from any alternate timeline. He will not need to know any details about the timeline to summon, but will need to be able to imagine what he is summoning and picture it in his mind. The object or person will then appear in front of him. He could summon an object which hasn't been created or invented in this timeline, or a person who doesn't exist in this timeline. He could also summon a person who does exist in this timeline, in order to gain access to different skills, opinions or thoughts developed in the different timeline. Occasionally a person could even have different abilities because of varying experiences and manifestation circumstances.
