While this was very clever, indeed, there was nothing about it that really made me think that it was Olema Surema until the reveal.
The birth defect, for example could have related to Ktulu because she was born with a birth defect, so it's not really specific to Olema Surema.
There are quite a few twins that are here in Helovia, so the two lines that represented twins could also represent other sets of twins.
Like I said, it was definitely very clever and Blu is willing to let you steal Olema Surema. Just let one of the admins know if you do decide to go ahead and take them so we can update the Throat's page :3
