I fear nothing. When Olaf left Labyrinth, he was the last original member of the band. When he formed Vision Divine, it was originally a side project, that grew to be greater than Labyrinth. He's seen many many musicians come and go. I appreciate his philosophy, though, that any musicians in his band must completely feel comfortable in the band and creating the same music. If they don't feel it, for any reason, then they should just walk away, and allow someone else to join who would fit the band's musical vision. Which is why he himself left Labyrinth. The band's direction as a whole was drifting from his own, so instead of throwing everyone out and starting new, he let Labyrinth continue as it naturally progressed. That's an honorable thing to do.
Besides... Vision Divine's grown to be such a stronger band than Labyrinth is, anyways!
