Heart Interior is a location in Torment: Tides of Numenera.
Background[ | ]
This is it, the heart of the Bloom. Here, it bonds, communes, and consumes...
Points of interest[ | ]
Commune with the Heart. You can ask for your companions' help, with Intellect (Persuasion), to gain access to their ability pools. To show it you mean business, you need to resist. Might allows you to rip one of the bloom-tongues out, Intellect to resist, and the Transdimensional Scalpel to slash it.
Next you can try to start forcing it into submission. Intellect does the most here, allowing you to search its memories, take control of its systems, and of course, search for Ishen. Probing the memories in-depth gives you a permanent +2 Intellect.
Locate Ishen with Intellect, then use it again to pull him out of the body of the Bloom.
After your commune is gone, the Bloom will also reveal that the Memovira is actually the First Castoff, Maralel. And Ishen is actually Mazzof. Talk to him to reveal quite a few secrets. You also receive the Frictionless Merecaster.
