My last post had a strange title in hindsight, not obvious in its meaning to all readers.
A roc is a giant sized eagle, from mythology.
A roc or rukh (from Persian رخ rokh[1]) is an enormous mythical bird of prey, often white, reputed to have been able to carry off and eat elephants.
I have been fascinated with them for quite a while. This fascination has come up again recently through my writing.
Since the roc is related to an eagle, or actually is a giant-sized eagle, it’s logical to use the term convocation for a troop of rocs, as per the terms of animal collectives and groups. I haven’t been able to find any images that due the giant sized bird justice. The best I could do was the following:
One of my Ars Magica RPG characters took upon the task to train a full sized roc. It was quite arduous and the bird ate a lot of food.
In the world of Dungeons and Dragons, it’s not a dire animal per se. The origin in its myth reside in Persian stories.

Dear Range,
I found your ROCS and I am really enjoy to see the pictures.
I do a kind of research about rocs. Do you know if they had any connection to China?
Would be really nice to hear from you,
hello from Germany,
Marion
I know that eagles are important in Chinese culture, but I haven’t found much information about giant eagles. That’s something you’d need to research further.
