This power is to Legend’s shard what Hero’s is to Stilling. You have the capacity to make devices that produce lasers with various effects limited by your creativity and the research you do.
Examples include lasers that can turn corners, fork into multiple lasers, pass through walls, freeze, ignite targets, cutting, disintegration, impact, heat, focused, staccato bursts, fat lasers, and invisible lasers. These are just examples though you could develop lasers with capabilities other than those examples and combine effects. Your power also isn’t limited to just these forms of esoteric energy manipulation and support technology the true purpose for this power is space travel so beyond dealing with harmful space energies, a form of ftl technology might not be out of reach especially if this power is whiteboxed.
