(When) Can Goblins Lie?

[MikMod]

Hi People! I would appreciate some viewpoints on this subject :)

I have an NPC clan of goblins and the idea that their leader wants to carry out some subterfuge to advance his clan. But how much can goblins lie?

• Can they create misdirection?
• What about false trails?
• What about planting false evidence?
• Or fibbing about their involvement and real motives?

And if one of the clan gets caught by the party, can they lie about what they have done? Under torture? Can they make false promises under some circumstances - if the stakes are high enough? And how uncomfortable does that make them?

Is it only a sworn promise that is 'guaranteed true' by goblin lore? Or does their essential honesty (?!) seep into all they do?

Many thanks!
