Shalleafa

The Ebony Grove
In his attempt to get Shalleafa to leave her room to discuss business with The Respectable Company, Jables mentioned to Shalleafa that Phes had burned down a patch of the surrounding forest with alchemist's fire, during the battle with the Yuan-ti.

Enraged, Shalleafa bound Phes to her service using some form of charm magic. Before she could enact her revenge, Phes agreed to atone and make reparations by planting new trees where the others had burned.

After the planting the Sharra druid Halcyon, cast a ritual enchantment making the ebony seedlings - and the surrounding forest for 1/2 a mile - grow unusually large, dense and bountiful for the next year. This new patch of enchanted trees is now known as the Ebony Grove.

The Withered Acorn
Shalleafa revealed that her sister's tree had died and all that was left of her is a withered acorn. Diranas and Mazeen made a deal with Shalleafa to use their research to attempt to revive her sister's tree if Shalleafa could provide morning dew gathered from sentient plants.
