Traits

A keyholes purpose is the regulation of internal saura, and for most Lockettes, one is sufficient for the task.  A singular keyhole is generally enough to let out excess saura that might lead to fragmentation of their shell, without leaking so much saura as to be excessive or endanger the wellbeing of the Lockette.

A keyholes purpose is the regulation of internal saura, and some Lockettes find themselves with many of those.  While this is commonly believed to be related to larger sizes of saura taking shells that are not large enough for them, there’s no conclusive evidence of that.  Lockettes with multiple keyholes often have to spend more effort on ensuring they keep their saura replenished than those with only one.

All Lockettes possess a keyhole of some sort to regulate their internal saura.  For most Lockettes, this takes the shape for which this trait is named, a simple hole as if for a key.

On occasion, Lockettes have a different shape of keyhole.  This can range from simple pawprints to a cracked open spot or a crown shape.  Lockettes do not always manifest with these types of keyholes - sometimes, a standard keyhole may experience enough damage that its shape breaks, or be lost entirely if it was on a limb that was fragmented completely away.  This is unusual, as the space around a keyhole is typically stronger than normal, but it is not unheard of…
