Stonekeeper <WIP>
Any being who possesses an Infinity Stone, knowingly or unknowingly.
While many Stonekeepers deliberate seek out Infinity Stones, in some cases the stones themselves will choose a keeper, as with Red Skull being made the keeper of the Soul Stone against his will, or the responsibility may be bestowed by someone else, as when Vision became the keeper of the Mind Stone when it was used in his creation.
In rare cases, a Stonekeeper may not be aware that they are a Stonekeeper, such as when Jane Foster became the host of the Aether.
Many beings have sought to become keeper of all five stones, most notably Thanos and the Collector.
