You've seen me often, know me well,
my name the scribes and sages tell.
My many kin you also know,
but I'm most famed, as our kind go.
One sister's love is grand largesse,
another's like me, more or less.
My brother shuns such grand appeal,
he much prefers his meager meal.
Our distant cousin's always in,
and that implies he's also kin.
And where one village holds another,
you'll often find our eldest brother.
I keep the peace with great panache.
Strike me down and neighbours clash,
or leave me be, it's all the same,
but tell me, friend, what is my name?
