Also, as a rule of thumb it's healthy to remember that roleplaying is a team sport, if you're ever under the impression your character could take on a couple of the other PCs from the very start then there is something wrong with the distribution of power.

Indeed. The intent was never to actually take PC abilities (without consent, unless given for plot purposes) but rather NPC arcanists, as given the plot there is no need for Two of a particular mage in a party, but one could always use a First Light arcanist. 

As for no one really knowing how it works, I considered this and wrote in the Order of Twilight Monks as part of a more ascetic group of arcanists who believe since the magnus varies from person to person, regardless of channeling point, their research is into the element of the self and its relationship to magnus. They do not directly study how to use it, but rather how it behaves and manifests in the Arcanist who uses it. A more quasi-mystic aspect of the art, rather than the pure science which is why they retreated into the Dusk Isle to hide themselves away from the more scientific community.

Thus it would be logical to state that Ibyxx knows his own magus (which was onset so late, but is a relatively simple technique requiring little variation) through the dedication of non-scientific study, he still is required to observe and study the techniques of another arcanist to actually learn the abilities before use. I had stated knowledge of how to use is not transferred, only knowledge of how it can work for the self which is gleaned through his study and knowledge of how to see into the understanding of Magnus. In essence, he has the formulas and equations required to solve for a complex expression, yet he does not know what the expression is until he finds this.

As for the science of the Magnus, if we take that Magnus is some form of variable conversion of energies channeled from a given source used to manipulate the universe around it to create, destroy or control forces and objects within the universe of which the exact mechanics are not well known (unified theory of Magnus) but known to require a conduit of will to be harnessed properly. In such consideration, it is not that the Arcanist holds inherent power in itself, but rather the ability to use power to the desire of the Arcanist. And since the Arcanist is observed to be for the large scale "unique" such that the same set of mental evocations produced variable results for the Arcanist, it can be argued that it is not the harness or method of channeling said power which sculpts the magnus, but rather this is unique to the one casting it. Thus by this line of logic, there is something inherent between the universe and the Arcanist who wishes to shape it such that the Universe would seem to "assign" identities to the Arcanist it interacts with as anyone with enough study can become a magnus, there is no special condition required to become a magnus user ergo one can surmise that the key relies in neither biological factors nor mathematical mechanics. Thus we can go into the question of what then makes the magnus unique and special to a given person if such cases hold true? I hypothesize it is the interaction between the caster and the world. As such I considered the main factor is simply what the universe permits the magnus to do given the identity of arcanist who casts it. Perhaps the universe knows the inner identity and self of the arcanist and thus grants that arcanist a particular magnus. The mechanics of this remains unknown and perhaps even arbitrary.

How it all ties in with Ibyxx is that his magnus works on creating a link between another arcanist and he. Such that when the universe sees him, it instead sees a psychic pointer directed at another arcanist within its system. So the Universe then treats him as said arcanist for spellcrafting purposes if he can formulate the combination of mental equations to use to get the spell desired.

Or at least that is what I came up with when I designed.
