an archetype i could build around:

Visionary (Dreamer, Prophet, Seer--see also Guide, Alchemist)

The Visionary archetype lets you imagine possibilities that are beyond the scope of your individual life and that benefit all of society. The Visionary brings into view what could be if certain choices are made, or what is inevitable given choices that have already been made. The Prophet proclaims a message associated with divine guidance, as in the Hebrew Prophets, some of whom also appear in the Quran. (Islam reveres both Jesus and John the Baptist as prophets). Both the Visionary and the Prophet engage their abilities in behalf of humanity rather than for personal use, but while many Prophets are rejected by the group they were sent to enlighten, Visionaries tend to be celebrated for their capacity to read what is just over the horizon.

The shadow Prophet or Visionary manifests as a willingness to sell one's visionary abilities to the high bidder, or to alter their vision to make it more acceptable to society. In extreme cases, tainted visions may lead entire societies into murderous or destructive rampages; then the Destroyer archetype may supersede the Visionary, as in the case of Hitler, Stalin, and Mao.
