1. The world is changing rapidly - Climate: Drought in the Fields, Endless Winter in Icewind Dale. Geological: Earthquakes in Elturel, Volcanic activity
  2. Strange creatures are appearing often from the adjacent planes of Shadowfell and Feywild, but some are from pure fiction (Gingawatzim don’t exist in 5e).
  3. Dragonborn are rare. They are thought to have arrived from Abeir about 100 years ago.
    1. Wizards know arcana about Abeir: a mirror plane of primordial elemental energy
  4. Gnomish inventions are exploding exponentially. Their engineered devices are starting to reproduce the effects of arcane spells.
  5. Some drugs synthesize metaphysical psionic abilities and the ability to see and contact creatures in other planes.
  6. Some cities are drawn to theocracy due to fear of undead.
    1. Elturel has become a religious autocracy based on fear of the undead. The Gift of Amaunator floats over the city like a second sun to keep the undead away. (See Descent into Avernus. Amauntor: a Netherese solar deity conflated with Lathander)
    2. Beregost is less autocratic but under the protection of Lathandar (Morninglord).
    3. Baldur’s Gate is a more diverse and chaotic ecosystem.
