There's a new activity live in the plot - The Infirmary. You can find it by clicking the red signpost in Taelia's Potion Centre. There are new achievements for this step.
IMPORTANT: This step will not work on Firefox.
This step is essentially a plot version of Charity Corner. You'll be donating potions from Taelia to heal the recovering Neopets. Currently, there is only the Jetsam available and it can only be healed using Taelias Concoction I (the others will be greyed out if you have them).
To use one, drag it over the Jetsam. You get an achievement for using one, three, and five potions. There is an FAQ for this section of the plot, and certain answers imply that the Jetsams needs may change over time, so this may become a daily (currently unknown).
The FAQ also implies that donating beyond the five needed for the achievements will be greater rewarded later down the line. This would make it the only uncapped activity in the plot so far, so it is currently unclear if this is the case.
