[@Necroes] I feel like you're overestimating how strong Lucius' psyker is, one. Two, and maybe a stupid question, but if they're attuned to telepathy specifically over all other forms of psychic power, even if those other powers are way larger in power usage, wouldn't they just detect any telepathically-inclined psyker that got on board the ship, or indeed any psyker whatsoever?
