[RPG] the lifespan of the Changeling race from UA: Eberron

I'm going to be playing a changeling (from UA: Eberron) soon, and my DM is excited to have this unique race as a PC, but I was wondering if there was some form of RAW on this sort of thing.

The Changeling race's Shapechanger trait simply states:

Shapechanger. As an action, you can polymorph into any humanoid of
your size that you have seen, or back into your true form. However,
your equipment does not change with you. If you die, you revert to
your natural appearance.

There is no age section in the Changeling race stats, and I am just curious as to what its lifespan and maturity rate would be. I thought that it could potentially be based on the species it is polymorphed into.

Let's say that this changeling has been in human form for 50 years. Has this form aged accordingly, or does it appear to remain the age at which you first polymorphed into it? Also, let's say that the form you've chosen has reached an elderly state; could said changeling simply polymorph into a much younger version of this form, prolonging its lifespan?

Best Answer

There isn't an officially stated lifespan for Changelings (as of writing this answer).

The most important thing to remember is that Unearthed Arcana material is only effectively playtest material. It's not "officially" published or polished and thus isn't nearly fleshed out as much as the core rule books or supplements so you're not likely to find that level of detail until it's actually put into a supplement book, if it even does.

There's only one other mention of changelings that I can find and that relates to doppelganger children in the Monster Manual but even that doesn't give us any information on their lifespan.

However, if you really want something to base it off and get a rough idea then it has been detailed in the 4e Eberron Player's Guide (unfortunately I can't speak for older editions):

Changelings reach maturity at about fifteen years of age, and they live about as long as humans do.
