I haven't dealt with arcane connections much, and the times I have have felt quite straightforward. But I realised yesterday that I am unsure what is meant by some spells that refer to "a place you have an arcane connection with" (Seven-League Stride) or "any place to which you have an arcane connection" (The Leap of Homecoming, and Rego Corpus guidelines Level 35).
Does this mean, for example, that a piece of my hair is fixed as an arcane connection in my lab, thus allowing me to transport myself there and other people there? It feels a bit odd that I can use it to transport other people there, but I can accept that.
Or, does it mean I need an arcane connection to the place itself, for example, a piece of the wall of my lab, or a flower that grows in that particular glade? This would seem to make more sense in terms of transporting someone to that particular place.
I can't remember exactly where, but I recall seeing other examples like this where I wasn't sure what "you need an arcane connection" meant, as in, a connection to what - to myself or to the thing in question? And where do I need it, on my person or in my lab or in some other place?
This may all be covered in the rules, but I haven't been able to find it. In fact, the Arcane Connection rules on page 84 only muddy the waters, as they say arcane connections allow the magus to cast spells on a target they cannot see. But for the Seven-League Stride, for instance, the location you need the connection to is not the target of the spell.
