2. Plant to Grow Thalamus

Acquire Origin Seeds from Chaos

After you have completed the Permeation of Witching Wards Incantation and inevitably died on the surface due to a curse that prevents you from staying too long, the next Chaos Gate you encounter in the Underworld will trigger an interaction where Chaos presents you with Origin Seeds.

This will be vital to completing the Incantation that allows you to stay in the surface indefinitely.

Acquire Through Digging Spots

You may also get Origin Seeds by digging the soil patches inside Chaos Gates.
