How do I reach the Forest?

[Hendrik]

Title. I just killed Hedgeward and I don't really know how to proceed. Any tips, please?

you could get there through the hive, or you can swim up the waterfall up the river, to the north in the city

Thank you so much! I discovered the Hive earlier but thought I couldn't continue without a new ability. Now I'm stuck on Chroma's last phase.

Edit: got it.
