This was originally made to be apart of an Undertale anniversary video back on DeviantART. It is now apart of two different videos found here https://www.deviantart.com/strikeyoko/journal/5th-LogTale-Anniversary-Community-Collab-897855053 and here https://www.deviantart.com/arerona/journal/Undertale-7th-Anniversary-929608698 Gaster (AU name Vedvulon), while as a commoner, is an expert mage that controls the lights and shadows around him to form his weapon of choice--a bow made of solidified light and darkness, thus a Nebula weapon made with arrows designed like shooting stars. The void orb by his hand acts as the handle where he pulls a string of light out of it and pulls back like one does setting an arrow on a bow string. Should he be finished with his weapon, he can easily dismiss it into starry particles as it disappears back into the air around it. The less light around him, the more visible his weapon is when in use.
