I am sorry to hear of your friend and corp member's passing. While we would not be able to discuss or offer access to the account or related information you would be welcome to have the character remain in the corporation. We would not remove the character or otherwise make changes to them so they can remain in their current corporation as long as no members remove the character manually. If you have any additional questions or matters we can assist with please let me know.

And if some TEST leader comes and complains why we have an inactive API key in corp he can go and have a nice long chat with me.
