Textual form of above: cyan = 0, 3, 7, 8, A, E, F, M, O, P, Q, X, Y, Z; green = 1, 4, 5, B, C, G, J, N, R, T, W; lilac = 2, 6, 9, D, H, I, K, L, S, U, V

5º 6.5h -- 12796
Use the letters. (Hint for previous hint.)
As a hint for hints 4 and 5, ARCHMAGE -- 7158 would be "GAME"
Hint 7: (still the last hint, but I will wait until the bounty is almost over to post my answer)
The last three hints refer to "MORSE" (as in Morse Code) and the stars clue leads to "POLLUX." Interpret that how you will!
Use the information given above this line to figure it out!
