I would probably be a diviner in search of "the otherworld" within the Pokemon World equivalent of the place I live in. And to explain what that would entail, I would have to explain a bit about this possible setting.
The land of Kaluai, based on the combination of ancient Finland, Kalevala myths & some of the more modern traits of my country, is a region divided between the South Kaluai that has started to develop its infrastructure & cities at the time of the setting leading to more urbanized environment & desires to develop its own Pokemon League Challenge, and the North Kaluai that still clings onto to the traditions of the land, with much of the population still communing with old spirits through spiritualism & shamanism.
As a diviner, it would be my job to commune with spirits and dispel spiritual imbalance as it appears. A job that is made harder by the conflicts between three feuding tribes that each call one of the three sacred mountains of the region their own. As with every practitioner of spiritualism in Kaluai, the ultimate end goal of the spiritual pilgrimage is the rediscovery of the "the otherworld", the Ancient Kaluai of legends residing in a separate universe from the one Arceus created where some spirits are said to pass on to according to Kaluaian myths. As a result, I would be wielding one of the two new types in the setting that are said to have originated from "the otherworld", typing I will likely call "Aeon" as to not make the western part of the fan base confuse it with Ghost-types.
