Remember to read the oerview at the end of all of my posts. They do outline in words all the details I can give.
The goblins on the path are all either asleep or dead. They are 25' in front of Lily and 50' in front of the rest of the party. Lily is ahead of the others because she is the only one that specifically said that she moved on the previous turn. Since nobody else said anything I assumed they stood where they were.
On a given turn characters get an action and a movement. (Sometimes a bonus action as well and technically an item interaction.) The "normal" think is to move, 25' for example is Lily's movement, and then do something like make an attack. However for your action you can do some things instead of attack such as dash, dodge or disengage. To dash is to run. If you dash you can run twice your normal distance. So, in Lily's case, if she used her action to dash she she could move 50' in one round. (Her normal 25' and then the additional 25'.) But then that would take her action and she wouldn't be able to attack.
If you take the dodge action it would also replace your attack - so no attack that turn. But then any attack made against you that turn has disadvantage - which means that for any attack targeting you I roll two 20-sided dice and then use the lowr of the two numbers rolled. It can be quite handy, but does mean you don't get to attack.
Using your bonus action to disengage means that instead of attacking you move away from an opponent for the round. (At normal movement rate.) Why do this? Because normally such a movment would mean any opponent engaged with you would get a free attack - an attack of opportunity. But if you disengage as your action they don't get those free attacks. But again, you don't get to attack yourself.
I will try to do maps in the future. The only reason I hadn't inthe past is that the image sourcing site I was using crashed.
