I had the same problem with the statues and I truly sympathize. It IS an error in the game and not something youre doing wrong. The upcoming FOV addon is suppose to fix that and a number of other issues in Ego Draconis.
Heres a thread where you can find the names of the statues (spoiler alert).
Keara's statue names You can try entering the names without having clues, I have seen others have limited success doing that, but it never worked for me. If that doesnt work, you will just have to leave Keara be and continue the storyline, which is not impeded if you dont kill her.
Good luck.
