Strange Omens and Portents

When destiny draws near or fates turn sour, signs of warning appear. Some are warnings to stay away others are invitations for heroes to face your doom. One god will send a warning while others want heroes to face their doom.

I wanted these results to be reversible for good or evil omens. Some tips to make omens good or evil included in quick types version.

Spells or prophecy might warn you with signs to look for.

You could add several together.

Omens mostly warn you  are displeasing a god or straying from a prescribed mission. Also might be warning signs of a curse or prelude to supernatural encounter or receiving a new quest.

You might receive a warning of the sign and what it represents so when you see it you expect trouble or a clue for your quest.

You might receive as a warning or invitation at a obstacle, river crossing or cross roads.

You might get a omen after an adventure as a enemy god scowls at you or good god salutes your actions.

An omen might warn of a petty god or demon or deity manifeting
