Before the game started, the following things were established:
Dhamon, a junior trainer from Cerulean City, was recommended and funded by his friend Bill to visit Professor Oak. There he would get expert advise to help him reach his goals.
Tiberius, a capture specialist in training from Viridian City, took a trip to Pallet Town to seek out and learn from Profesor Oak.
Tekrahkshi, a ranger cadet from New Bark Town, asked by Professor Elm to deliver a package to Professor Oak because Elm couldn’t reach Oak via phone for days and thought something was strange. He gave Tek his Cyndaquil to help him on his delivery trip.
