It took him around 4 hours to finally find something close to his expectations in the surrounding area, as he found a small cave underground.
It was previously home to a rank 2 Iron Bear, which was unable to last more than 20 moves against Roy and lost his life.
Roy quickly put the big thing inside his Storage Ring, that he had only been able to easily control after opening his 'sense area'.
Even though the ring belonged to him right from the start, Roy was unable to use it properly, due to his lack of control over his spirit power.
It was the same as possessing the keys to a big storehouse but being unable to lift anything inside it to transport it outside, and the same way about taking something outside and place it inside.
The entrance to Gaia was different, as it was his own physical body that made the connection, and what opened in front of him was a door that allowed him to go through.
